To determine blood oxygen (arterial blood oxygen saturation (SpO2)) and pulse rate, many biosensors use the reflectance of red and infrared (and sometimes green) light. Based on photoplethysmography (PPG), an optical technique that measures blood volume variations, dual-wavelength PPG pulse oximeters noninvasively measure/calculate the arterial oxygen saturation (SpO2). An oximeter transmits radiation at a known […]

Digital isolators comply with VDE and UL safety standards.
STMicroelectronics has extended its family of dual-channel high-speed digital isolators, enhancing flexibility for designers to optimize their board layout. The new STISO620 contains two channels of the same directionality, having all digital inputs on one side of the isolation barrier and all digital outputs on the other side. . It joins ST’s digital isolator lineup alongside the STISO621 and […]
32-bit microcontroller family is low-cost alternative in 8-bit applications
STMicroelectronics is again broadening access to its STM32 microcontroller (MCU) family by introducing the most affordable series yet: the STM32C0. STM32 MCUs are used in billions of smart industrial, medical, and consumer products worldwide. With thousands of existing STM32 part numbers, product designers can select the features and performance they need at a price to suit […]
CES roundup: Products for engineers
From capacitors to test equipment, engineers can find components that consumers don’t even know are inside their gadgets.
MEMS microphones, dev kit feature low power, wide range
TDK Corporation announces the availability of the InvenSense T5838 and T5837 MEMS microphones, and the SmartSound One Development Platform. These MEMS microphones push the boundaries of microphone acoustic performance, power efficiency, and advanced feature sets all in small package footprints. SmartSound One offers a solder-free, plug-and-play interface to evaluate and develop multiple types and configurations […]
Linux platform supports RISC-V embedded development
Siemens Digital Industries Software announced that its Sokol Flex OS software now supports RISC-V embedded development with the availability of one of the industry’s first commercially supported, extensible, and customizable Linux platforms for the RISC-V architecture. Based on the popular, open-source Yocto Project industry standard, Siemens‘ Sokol Flex OS helps embedded developers create customized, Linux-based […]
Power shunt resistors come in pint-sized 0508 package
Rohm Semiconductor announces the LTR10L series of wide terminal shunt resistors, optimized for a variety of applications in the automotive, industrial, and consumer sectors. ROHM has also strengthened their considerable lineup with two updated general-purpose MCR series shunt resistors (MCR10L and MCR18L). In recent years, high-efficiency operation has been required from the viewpoint of energy conservation – not […]
5G SoC pushes gaming, extends battery life
Mediatek’s Dimensity 8200 CPU/GPU/modem features eight CPU cores, six GPU cores, and LPDDR5 memory to boost gaming and video.
Automotive-grade chip resistors excel at handling pulses
High-reliability chip resistors can be more difficult to find and even more so when there are pulse handling requirements. Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance. Stackpole’s recently released RPCA series addresses all these needs. The RPCA has limited to […]
Audio power amps designed for automotive applications with power levels up to 10 W
STMicroelectronics’ FDA803S and FDA903S are the newest single-channel fully differential 10W Class-D audio power amplifiers in the STMicroelectronics FDA (fully digital amplifier) family. They are designed for automotive applications like eCall, telematics, and wherever an audio channel needs to reproduce human voice, music, or warning messages at a standard output power level of up to 10W. The […]
